The BBC will be mightily delighted than Hans Rosling's The Joy of Stats has proved such an unliklely hit online. Nearly a million and half views in a couple of weeks for a BBC4 clip – shurely shome award?

And it would be remiss of us to overlook the latest Funny Cat Video, though I imagine you're growing as sick of them as we are with "flashmobs". It's the penultimate Viral Video Chart before Christmas, so doubly enjoy yourself.
